Weird Noise from under Frunk

[ProximusAl]

Let me start by saying, this is not the normal bubbling/gurgling sound you would hear when doing FDRS updates, but something else.

Twice now, when I’ve gone to or from my car, roughly under the top beauty cover (had frunk open at time) I’ve heard what can be described as the following:

Electrical arcing type noise (I’m sure it’s not this, but gives you a hint)
Most sounds like when your sucking a straw at a very nearly empty glass.

Car ignition is fully off.

Is it possible there is some coolant fluid reservoir under the top beauty cover that it teetering on near minimum making this sound?

Its quite a disconcerting noise. My car is fully FDRS’d up, and no warnings or DTCs are showing, so I feel this is something “fluidy”

Anyone heard of this or ideas?

I’m trying to record the noise on my dog n bone but it’s so sporadic I’ll be lucky to catch it

I’m not much help here, but take a look at these pics I posted earlier this week of the front end disassembled. There are a couple fluid reservoirs there. Any of them match up with your sounds?

Almost sounds like a Western Digital hard disk that’s on its way out. I could remove the beauty cover but would have to leave it off as the noise is hard to recreate. Just pure luck I caught it then

You're positioned right above the ABS HCU (hydraulic control unit) which does make some clunking sounds when the car is first woken up. However yours sounds broken. This is what mine sounds like when the car is woken:

EDIT: Just realized I've never seen a picture under the hood with the frunk removed of a RHD Mach-E. I don't know which things would have switched sides compared to a LHD.

Sounds plausible. It could well be that, as I never start the car but opening the doors sometimes causes it. I would have thought if it was broken it might fire off some warnings/DTCS. The car drives fine.

Hi there! Will you send us a message with your VIN and your local Ford dealer? I can look into things on my end.
